.iBe it' known that. we, JOHN; TAYLon and 'EDWIN \VILLIAM BL'QKLEY, subjects of thc Ki0fGreitt Britain and Ireland, residing at 'ewton Heath, Manchester, in the county qfuLancasliire, England, have invented new and! useful Improvements in Mechanical Warp Stop-Motions for 'eaving-Loonis,

Wa' ing-Machines, and the Like, of which the ollowing is a specification. Th1s invention has for its ObJECt improvements" in mechanical waip stop motions for.

weaving looms, warping machines and the like, and relates to that type of such motions in which drops consisting of metal strips are used in conjunction with a fixed notched or serrated drop bar and a second similar bar or inset which is movabie in relation to the fixed drop bar, the fall of a drop causing the two bars to be locked together and thereupon the motion of the loom to be stopped through connecting mechanism.

. The present invention has been designed with the object of so constructing a warp stop motion of the above described type that'it shall occupy onllv a small spaceand contain but few parts, shall be sinrple,-n1ore easily-adjustable and less liable to wear, shall be independent of any of the so-call'ed going or reciproca-tirhg-parts .-.of.-,-.the -loom' such" as the fliay and its sword, shall enable ;a flexible connection between itself and the shipper or knock-off lever to be used in place of a series of levers, and by reason of it being self-contamed-shall be capable of being readily at-,

tacl'fed' to and removed from a loom, of almost any description, without alteration in an ofits main parts. Y

n" addition to the foregoin advantages our invention will be foundto have especial value-in the case of warp stop m otions'for looms'in which, owingto tlie' fi11cness of the counts of warp used ,-a large numberof drops andseveral drop bars are rendered necessary, "as additional bars may be added with fac lit 1 *1 i r r t ccording to our invention we so arrange i i 'the 'operative parts of our nwarp stop motion that, hil'et'hey are independent ofthea'lay and itssword and other l'CCiPlOCfltlllg parts at the loom, a part carried by or connected to rocking lever or other means factuatmg the inovabl'eserrated' bar or inset shall -du ring I jthe normal running ofthe loom be so timed Specification of Letters Patent;

as to miss a constantly moving actuator, but upon the movement of said serrated bar or inset being-arrested by the fallof; a drop the part carried by oncoi'mectcd to said rocking lever or the like shall come within the path of said constantly moving actuator, be moved thereby and so cause disengagement of the shipper lever from its retaining notch.

The preferredconstruction of the, motion is shown bythe accompanyingdrawings, in which v I Figure 1 is a side elevation of a portion of one of the side frames of aloom and. showing the applicationof the invention, parts of the loom being omitted for the sake of clcarncss. Fig. '2 is a front elevation of the two side frames of a loom, illustrating how the drop bars are supported at the side of the loo m opposite to that to which the motion is secured. Figs. 3, 421ml 5 are views of a portion of the shipper lever and means for releasing said lever from its retainin notch. Fig. 6 is a view of one form of drop t mt may be employed.

of the loom, 2 the cam shaft, 3 are-the pick- 10 are the fixed serrated drop bars, 11 are the movable serrated drop bars or insets and 12 are the drops, these parts being common to the hereinbefore mentioned type of stop motion.

- In carrying out the present invention we employ a frame or casting 13, which is so constructed as to support all the chief parts of the motion roper and to bereadil attached to one of the side frames 1 of the oqm by one or more bolts 14.

15 are curved horns on the inner side of the casting 13 which are formed with slots 16.

17 are screwed. pins which pass through the fixed serrated drop bars 10 and through the slots 16 in the horns 15, and 18 are nuts on the outer ends of the ins 17. v

, 13, Fig. 2, is a brac et secured to the other side frame1" of'the loomand formed with horns 15' and slots 16 similar to 15 and 16.

17$, are screwed pins passing through the other end of the fixed drop bars 10 and the slots 16, and 18 are nuts on the screwed pins 17?. By means of said horns,,slots, pins and nuts the serrated bars 10 and their insets 11 can be adjusted and secured in position without having to alter the position of the castings 13, 13, or interfere with the means by which the motion is driven.

19 is a horizontal shaft which is supported within bosses 13 at the lower part of the castin l3, and is driven from the cam shaft 2 of t'e loom b means of a rope, belt or chain 20 and pul e s 21 and 22.

23 is a constant y moving actuator, which is mounted on "the horizontal shaft 19 and pulley 22, and the cam or actuator 23 and the osses 13" by means of the screw 22 and the in 23 b which said pulley and cam are fixed .to the horizontal shaft 19. The hori-. zontal shaft 19 is provided with an eccentric 24 upon which is mounted the enlarged end 25 of a connecting rod 25. The eccentric 24 is preferably formed separate from the horizontal shaft 19 and is secured thereto by a screw 24, as shown in Fi s. 14 and 15.

26 is a vertical rock sha t which isr suppo'rted within a boss 13" of the casting The rock shaft 26, which is shown separately in Fig. 16, preferably consists of a pm which is Figs. 20, 21 and 22 is formed wit formed'at its upper end with a head126 and is secured in position within said boss 13" by means of a pin 27 and clamping screw 27..

The piece 27, which is shown se arately in ii two projections or arms 27 and 27', The arm 27 terminates in a curved head 27 which snugly fits withinan orifice 25" "in the outer or smaller end of theconnecting 1'00 25, this construction of head and orifice forming a species of ball and socket joint by means of which the movement imparted to the connecting rod 25 by the eccentric 24-istran'sferred to the rock shaft 26. The movement so im arted to the rock shaft 26 is transmitte to a normally moving part. Said normally moving part preferably consists of a rocking lever 28 which is mounted on a spindle 29 supported in lugs 13 on the casting 13.

The arm'or pro'ection 27 of the piece 27 is somewhat yiel ingly connected to the lower end of the rocking lever 28 by means of two flexible arms 30, consisting of su erposed thin metal stri s, which bear on asp Ierical swell 28 at the ower end of the rocking lever 28; and are secured at their inner ends to said rojection 27 and at their outer ends by a distance piece 31. The upper end of the rocking lever 28 is detachably connected to a pin 32 fixed to the movable serrated inset,

ar or bars .1 1 by any suitable device such as a latch 33 pivoted at 34 to lugs 28 on the upper part of the rockin lever 28. :The latch 33 is provided at its ont end with an olplen slot35 which is passed over the in 32, t 's arrangement of pin and ivote latch enabling the movable serrated ar or-bars 11 to be readily disconnected when required from the moving parts of the motion and the latter to be so-renderedinoperative. Any suitable number of movable sei'ra'ted bars or insets may be connected together by a single pin,-such as 32, and be operated from a common rocking lever. The rocking lever 28 is provided with a sliding rod 36, which projects at its lower end into the path of the actuator 23 and is located at its upper end 105 below a plate or lever 37 pivoted at 38 to the casting- 13. r V n For the urpose of simplicity of construction and of facilitating the mounting of the rocking lever 28 within the. casting 13, the 110 sides of the rocking lever fit, as shown in Figs. 7 and 8, closely against the lugs 13 and I the rocking lever 28 is secured in position within the casting 13 and fixed to the s indle 29 by passing the sliding rod 36 throug i said 115 spindle, as clearly shown in Figs. 7, 9, 10 and 18, downward movement of the sliding rod 36 being limited by a pin 36. The pivoted plate or lever'37 is connected by means of a wire or other flexible medium 39 to atrip- -120 ping device adapted to release the Shipper lever' 8 from its retaining notch 9. The pre-' ferred form of tri ping device is that shown by Figs. 3, 4 an 5. Said tripping device consists of a bell-crank lever 40 which is pivthe actuator 22) and the other parts of the motion are sotilncd that during the normal running of the loom the sliding rod 36 is not raised by said actuator.

A motion constructed as above described can he applied without alteration of its parts to what are known in the trade as righthanded and left-handed looms.

The operation of the motion is as follows: \Yhen from any cause a drop falls on to its fixed drop bar and into the notches or serrations in the lived and movable drop bars the travel of the movable bar or bars and rocking lever is arrested. and as the horizontal shaft and vertical rock shalt continue to move the actuator on the former will come. into contact with the sliding rod carried by the rocking lever, will raise same and through the llcXible connection disengage the shipper lever from its retaining notch and stop the loom. the yielding connection between the vertical rock shaft and. the lower end of the rocking lever permitting the former to move and the latter to remain stationary with its sliding rod in the. path of the actuator on the horizontal shaft.

\Yith a view to facilitating the nn'ninting ol' the driving i'nlley 21 on the cam shaft 2 and. its removal therefrom and to avoid interference with the arrangement of other parts oi theloom said pulley is constructed, as

shown in Figs. 23 and 24, in two halves which are connected together by a dovetailed joint 21 or equivalent device, so that said halves may be readily locked together and mounted and slid on said shaft, the two halves of the pulley 21 being held together by the rope, belt or chain .20. The pulley 21 is somewhat loosely mounted on the cam shaft. 2 and is driven, by the ordinary long key 4 which secures one of the tic-king cams 4 and projects beyond same. 'I he above described construction of split pulley 21 enables the pulley not only to be easily mounted on the cam shaft 2 but also to he slid along same or removed therefrom, when the key 4' can be easily removed for the purpose of adjusting said cam 4.
